A student claims that hitting a tennis ball across the court is an example of balanced forces. Is he correct?(1 point)
Responses
Yes, because the force in the direction of the ball’s motion is greater.

The student is incorrect in claiming that hitting a tennis ball across the court is an example of balanced forces. The correct answer is "No, because the force in the direction of the ball’s motion is greater."
To understand why, let's first define balanced forces. Balanced forces occur when the forces acting on an object are equal in magnitude and opposite in direction. In other words, the net force acting on the object is zero, resulting in no change in its motion.
When hitting a tennis ball, a player applies a force in the direction of the ball's motion. This force is greater than any other forces acting on the ball, such as air resistance or the force of gravity. As a result, the net force on the ball is not zero, but rather in the direction of the applied force. Therefore, the forces on the ball are unbalanced, leading to a change in its motion.
Hence, the student's claim that hitting a tennis ball across the court is an example of balanced forces is incorrect.
